FAQs
Installation requires respecting the EEx d gland specification for Zone 1 environments. Use the provided gland to achieve proper sealing against dust and moisture, ensuring the inner/outer sheath ranges (7.0–12.0 mm and 10.5–16.0 mm) are compatible with your cable size. Follow Eaton's installation sheets for torque, crimping, and strain-relief guidance to maintain IP66/IP68 integrity.
Yes. The connector is designed for #16 AWG conductors with crimp termination and silver-plated copper contacts. This arrangement minimizes contact resistance, supports reliable current transfer up to 18 A, and helps maintain connector performance through repeated mating cycles in harsh environments.
The CEX-133A212-355SN carries IECEx/ATEX Zone 1 certification, IP66/IP68 ingress protection, and NEMA 4X 6P ruggedness. It is designed for hazardous/classified locations such as chemical plants, oil and gas facilities, mining operations, and other environments requiring certified, sealed electrical connections.
The combination of a robust EEx d gland, sealed IP ratings, and rugged shell reduces ingress risk and limits maintenance frequency. Its 12-shell, 10-contact arrangement supports scalable wiring, while the unarmoured cable compatibility and crimp contacts simplify field servicing, enabling faster replacements and less downtime during outages or routine maintenance.
Key challenges include maintaining seal integrity in Zone 1 areas, accommodating a range of cable jackets and inner/outer sheath sizes, and ensuring reliable current transfer with flexible wiring. This plug addresses them with a gland-based seal, well-defined cable ranges, and durable silver-plated contacts, reducing risk of arcing, moisture intrusion, and connection failures.
